M=-2
and containing
with a slope
p (7,3)

Step-by-step explanation:

I can't get your question ,but if you are asking for the equation of a line with the coordinates (7,3) and gradient m = -2

we use the expression

y-y1 =m (x-x1)

substitute the y1 and x1 coordinates and gradient in the formula

y -3 = -2 (x-7 )

y-2 = -2x +14

y=-2x+14+2

y=-2x+16

rearranging

2x+y-16=0

therefore the equation of that line is

2x +y -16 =0

gregory's graph is incorrect because it shows 2 inches of growth for each week when it should show 0.75 inches of growth each week.

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)
